Currently, we check for register multiwrites during packet decode. The
downside of this approach is that it only checks a single destination
register for each instruction. During analyze_packet, we can check
for more than one instruction. Further, we can check for different
types of registers. This series adds checks for HVX v-registers and
q-registers.
Note that multiple writes to a predicate register are allowed on Hexagon.
Taylor Simpson (8):
Hexagon (target/hexagon) Move code out of gen_start_packet
Hexagon (target/hexagon) Check for GPR multiwrite in analyze_packet
Hexagon (tests/tcg/hexagon) Add tests for multi-destination
instructions
Hexagon (target/hexagon) Check for vreg multiwrite in analyze_packet
Hexagon (tests/tcg/hexagon) Add tests for vreg multiple writes
Hexagon (target/hexagon) Check for qreg multiwrite in analyze_packet
Hexagon (tests/tcg/hexagon) Add tests for qreg multiple writes
Hexagon (target/hexagon) Remove old way of detecting register
multiwrites
